He made it six goals for the season and Martinez reckons Everton can always turn to the Belgium international in their hour of need.

“He has an elite brain and you can see when he puts his mind to it he can achieve anything,” he said.

“I always said Rom has got that unique strength of being the man the team needs and in the second half it wasn’t a coincidence he was the one who scored the goal straight after.

“When you score two goals and you get an assist it’s impressive. When you look at the way West Brom defend they are very good in what they do. He had a real desire to get on the end of the crosses and it made a real difference.”

Romelu Lukaku: Key to Everton’s remarkable comeback against West Brom

It was the first time Everton had come from 2-0 down to win a top-flight game in 21 years – when they beat Wimbledon 3-2 in May 1994 to stay in the Barclays Premier League.

They had to come back after goals from Berahino and Dawson put the Baggies in control at The Hawthorns and Martinez admitted they were not good enough in the first half.

He said: “We were sluggish and we were sloppy. At half-time we had to reset and refocus.

“I spoke before the game and I knew we were going to score but we knew Tony Pulis’ teams are incredibly well organised.

“Our first-half performance wasn’t up to the level, every player was off two or three per cent. We were quite loose and quite ordinary.”
